Major Darwin road to get $100m upgrade

The Northern Territory Government says $103 million will be spent on duplicating Tiger Brennan Drive, which links Darwin with Palmerston.

The Treasurer Delia Lawrie says the Federal Government will contribute $70 million while the Territory Government will spend $33 million.

She says the entire project will take three years to complete and traffic delays and bottlenecks are unavoidable.

"You have to get in there and deal with the duplication," she said.

"The roads guys do it as best they can, they work long hours, try and do most of the work outside peak.

"They do traffic management around it and they actually design the project understanding the traffic flow issues."

The Treasurer says the two governments have also agreed to spend $106 million on regional roads.

"$90 million from the Commonwealth and $16 million sitting in there from the Territory Government to improve Port Keats, the Buntine, the Roper, the Central Arnhem Road, the Arnhem Link Road and the Santa Teresa Road.

"So not just a strong investment in town but also a strong investment across the bush."
